Nightmares!

Laurie woke the group up in the early hours of the morning with a piercing scream. Waking up in a sweat, she was calmed down by the girls before the boys rushed into the girls bedroom. She confided in Michael, Maria and Isabel that she still had nightmares about an event that happened at the beginning of the year.

What that event was she didn't allude to, however, it seems that her fellow housemates were fully aware of the circumstances.
